Buildings With Their Own Internet Identity and

Address

Where should we locate our Web-Based Facilities Operation "WBFO"?

Documenting the Design Variance

Buildings are seldom operated as they were originally

designed.

We must develop the “magic” to take our

automation interfaces to the next level in an

elegant convergence model.

It is all about abetter interface with the end-user.

I predict a very strong movement to "occupant integrated" HVAC controls within the next decade.

My prediction is that by the second decade of this century, most class "A" office spaces will be required to offer individual control of thermal and lighting levels. This integration will most likely be Internet based.

Thomas Hartman, P.E. Contributing Editor, Friend and Mentor

Occupants are connected to wide area networks, including the Internet, and yet almost none of them can connect to their local comfort system to request changes in thermal or lighting levels in the space they occupy. 

From a worker performance perspective it is extremely wasteful that we arenot aggressively pursuing suchindividual comfortcontrol connections. 

WHY A WEB-BASED INTERFACE? 

• Easy access.

• Cost of ownership.

• Ease of installation and configuration.

• Common 'front-end' to dissimilar systems.

• Extended life of existing EMS.

• Scalable.

We are not talking about viewing our old systems

through a Web browser; we are talking about total

product, design, control, and mechanical/electrical

equipment integration.

Have you seen the new CABA Technology

Roadmap for Intelligent Buildings?

If we do not change,

changes will come from outside our

industry.

The real danger for our industry is if we do not grow rapidly enough to provide this value added service there is a host of "ISIT's" (Information Systems and Information Technology) types who will.

Avoiding Network Clutter

• Standardized protocols

• Use managed network hardware

• Know the domain of use

• Derived vs collected data

The OSI ModelLayer 7: The application layer...is where communication

partners are identified

Layer 6: The presentation layer...is usually part of an operating system

Layer 5: The session layer...sets up, coordinates, and terminates

Layer 4: The transport layer...manages the end-to-end control

Layer 3: The network layer...routing of the data

Layer 2: The data-link layer...synchronization for the physical level

Layer 1: The physical layer...conveys the bit stream
